a backup program for android. requires root and allows you to backup individual apps and their data. both backup and restore of individual programs one at a time and batch backup and restore of multiple programs are supported (with silent / unattended restores). restoring system apps should be possible without requiring a reboot afterwards. oandbackup is also able to uninstall system apps. handling system apps in this way depends on whether /system/ can be remounted as writeable though, so this will probably not work for all devices (e.g. htc devices with the security flag on). backups can be scheduled with no limit on the number of individual schedules and there is the possibility of creating custom lists from the list of installed apps.copy the busybox binary to your system, for example /system/xbin or /data/local, and make it executable. symlinking is not necessary for use with oandbackup. in the oandbackup preferences, provide the whole path to the busybox binary, including the binary's file name (e.g. /data/local/busybox).
